Beat Blades Haruka

Takamaru was living an ordinary life, looking for love. Despite the valiant efforts of his landlord's daughter, Narika, to get in the way, one day Takamaru falls for a girl named Haruka at first sight. That very evening, Takamaru and Narika are attacked by a mysterious group of ninjas called the Noroi only to be saved by none other than Haruka, clad in kunoichi gear. It turns out that Takamaru is the heir to a clan of heroic ninjas known as the Crescent Moons and as such he has the ability to provide a supernatural energy called SP through a ritual called Dragon Synergy. Thanks to Takamaru's generous "assistance", Haruka manages to fight off the ninjas, but this is only the beginning of their long and arduous battle.
